Viewings (Naiken): What to Ask and What to Watch For

Japan apartment viewing tips start with one premise: a 15-minute naiken decides what months of tenancy feel like.¹² Photos hide weak water pressure, dead phone zones, and thin windows, so this guide turns the short appointment into a repeatable test-and-ask routine.

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

Overview

A naiken is an in-person visit to a rental unit before signing, arranged through the mediating agency to check the interior, the building, and the surroundings beyond photos and floor plans.¹³ It applies to any prospective renter at the pre-application stage, regardless of visa status or nationality.

Appointments are short. Practitioner sources describe 15 to 20 minutes as typical, while one agency source describes 30 minutes to one hour including measuring and the office debrief, so plan for triage rather than a leisurely inspection.²³ Touring several shortlisted units in one day is normal, and daytime visits are best because light and room feel do not transfer from photos.¹⁴

How a Viewing Appointment Works

The agency sets the date, gets owner permission, and walks you through the rooms and shared areas.¹ You can tour multiple properties in one day by telling the agent your shortlist when booking.³ After the tour you return to the office to discuss details, apply on the spot if the unit fits, or politely decline.³

Bring tape, phone, and papers to move fast

Good units move on a first-come first-served basis, so a tape measure, a charged phone, and ready application papers let you apply right after a strong viewing.¹³

What to bring and viewing manners

Bring a smartphone for photos and signal tests, a notebook and pen, a measuring tape, and slippers for the entrance.³ Carry ID and a personal seal if you might apply immediately after the viewing.³ If you have the floor plan, write measurements directly on it.³

Remove your shoes at the 玄関 (genkan, "entrance vestibule") even for a short look, since stepping inside with shoes on is not allowed.¹ Ask permission before photographing or filming, and do not upload unit photos publicly for privacy reasons.¹

Assume tap water cannot be used in a vacant unit unless the agent confirms otherwise.¹ If plans change, notify the agent as soon as possible because transport and owner permission were booked for you.¹

What to Test Inside the Unit

Work in a fixed order so the clock does not decide for you. Test signal, water, windows and noise, storage, and kitchen space, then use remaining minutes for questions.²⁴

The viewing flow looks like this:

Water pressure and hot water heater

Turn on the taps and flush the toilet to test water pressure, since older buildings can run weak and the difference shapes daily life.⁵⁴ Inspect the kitchen, bathroom, and toilet for cleanliness and drain odors, and ask about water-related maintenance history because post-move-in water trouble gets expensive.³

Check the hot-water heater label for its model year where visible, since older units break down more easily and use more energy.³ The 給湯器 (kyūtōki, "hot-water heater unit") generally lasts around 10 to 15 years, with unstable temperature, strange noise or vibration, higher gas use, or reduced flow as replacement signals.⁶

Match the stove and heater to the gas type

City gas and LP gas use different appliances and connectors, so confirm which gas the unit uses before buying or assuming anything fits.⁶

Mobile signal and internet readiness

Test your phone in the living area, hallway, and entrance, plus each room corner, the kitchen, the toilet, and the entryway where time allows.⁴³ Concrete structures can block signal in specific corners, so one bar at the door does not prove the bedroom works.⁴

Ask whether building fiber already exists or a new installation is needed, since practitioner sources describe separate installations as taking 2 to 4 weeks (limitation: single agency-blog figure, no carrier primary).² Count power outlets and mark their positions on the floor plan as you walk.⁴³ Confirm lighting fixtures and the intercom as part of the same equipment sweep.³

Air conditioner and window seals

If an エアコン (eakon, "room air conditioner unit") is installed, switch it on, check airflow and cooling and heating response where power allows, and listen for unusual noise.² Open the windows to check airflow, then stand still and listen for traffic, trains, neighbors, upstairs steps, and hallway doors.⁴³

Test every window and door for closing, locking, and sealing, since older frames can warp and leave gaps.² Check corners, window frames, and the wall behind a future fridge for stains, mold, or damp smell, with extra care on first-floor and north-facing units.² For roadside or trackside units, judge insulation directly rather than trusting the listing.³

Kitchen stove type and kitchen space

Check the kitchen in person instead of trusting photos. Smaller units often have only 1 to 2 burners with a stovetop and no oven, plus less usable counter than the wide-angle shot suggests.²

Many older units provide only the countertop space and gas taps, so the tenant brings a 1-burner or 2-burner tabletop stove matched to the unit gas type (practitioner-described norm; no government primary states it as a rule).⁶² Measure fridge and washing-machine bays including width, depth, faucet height, and the washing-machine pan inner size, plus entrance width and large-furniture routes.³

Open every closet and judge depth and shape, not just count, and confirm kitchen, entrance, bathroom, and living-room storage placement.⁴³ Storage decides whether a small plan lives clean or cluttered.⁵

Check	How	Pass signal
Water pressure	Run taps, flush toilet	Steady flow, fast drain54
Hot-water heater	Read model-year label	Well within 10 to 15 year life6
Mobile signal	Test each room and entryway	Usable signal everywhere43
Aircon and seals	Power on, open and lock windows	Airflow, quiet, tight seal2
Kitchen and laundry	Count burners, measure bays	Stove fits gas type, appliances fit23

The table above is a memory aid, not a substitute for the section tests. Walk it top to bottom when minutes are short.

What to Ask Before You Leave

Unasked questions become move-in surprises. Pin dates, cleaning, association duties, and trash rules before leaving the building.⁵⁷

Actual move-in availability and cleaning status

Ask for the exact earliest key-handover date, not a vague available-now. The normal flow from viewing through application, screening, contract, payment, and handover takes roughly 2 to 3 weeks, longer in peak season or with incomplete papers.⁴

Ask whether the unit was cleaned recently and what cleaning happens before handover. Raise any visible defect as a pre-signing repair or cleaning condition instead of accepting it silently.² Confirm window direction, what sits directly outside, floor-level shading, and balcony direction and drying use, since south-facing rooms run brightest and most in demand.²

MLIT advises confirming before signing who bears room-cleaning and key-exchange costs when they appear as special clauses, plus the scope of 原状回復 (genjō kaifuku, "restoration to original condition").⁸ Keep the signed contract until move-out procedures finish, since settlement references it.⁸

Do not sign with open viewing questions

A licensed agent must explain important matters before the contract is concluded, so resolve untested items or vague answers before sealing anything.⁵

Neighborhood association and trash-day schedule

Ask which 町内会 (chōnaikai, "neighborhood association"), also called 自治会 (jichikai, "residents association"), covers the building and whether membership is expected in practice.⁷ Joining is legally voluntary and you can leave after joining, but daily life runs through the association in many areas.⁷ Typical duties include garbage-station cleaning and management, festivals and events, disaster drills, and the 回覧板 (kairanban, "circulating notice board").⁷

Item	Amount	As of	Notes
Monthly association fee	Around 500 yen, some areas above 2,000 yen	2024-067	Varies per association; sometimes yearly lump sum or folded into management fees

Association fees vary by group (as of 2024-06; confirm current figures with the building manager or association). The table above covers the whole fee picture, so no further currency note is needed in this section.

Non-members can face practical friction. Some stations restrict non-member use or condition it on joining cleaning rotations, and non-members miss the circulation board.⁷

Ask for the fee, duties, and garbage-station location, walk the station route once, and judge station cleanliness as a management signal.⁷⁵³ Trash sorting and collection days are municipal rules, so confirm against the ward or city calendar and the building collection point rather than carrying one area answer to the next search.⁹

Reading Agent Signals and Red Flags

Treat evasive or rushed behavior as data. It does not prove a defect, but it tells you where to demand specifics in writing.²⁵

Signals that hint at undisclosed problems

Watch for a tour that skips rooms, deflected answers on noise, damp, or complaint history, and reluctance to itemize fees or put follow-ups in writing.²⁵ Pressure phrasing such as someone else is applying now, without specifics, is a signal to slow down rather than hurry.⁵

Walk-away signs include a damp or moldy smell, tested weak water pressure, thin windows plus street noise, unusable storage, and a chaotic or dirty garbage area.⁵ None of these are pickiness. They predict costs and friction you would inherit.⁵

If the agent cannot answer on management policy, noise history, or utility averages on the spot, ask for a follow-up email before signing. Reputable agencies answer in writing, and the written reply becomes your later reference.² The formal 重要事項説明 (jūyō jikō setsumei, "explanation of important matters") before signing is the last point to clear every open question.⁵

Good to know

The 15-minute clock forces triage, not thorough inspection

Short appointments punish browsers and reward checklists. Run signal, water, window and noise, and storage checks first, since photos and floor plans cover layout and finishes later.²⁴ Viewing 3 to 5 units adds comparison context that makes an outlier unit easier to spot.²

A vacant unit with utilities off limits what you can test

Vacant units often have water shut off and no power for aircon tests, so some checks may simply be impossible on the day.¹³ Name what could not be tested before leaving, and ask for a second check or written confirmation rather than guessing.¹²

Trash and association answers differ by ward and building

Sorting calendars are municipal and association fees and duties are per-group, so re-confirm both for each candidate unit.⁷⁹ A correct answer for one ward or building does not transfer to the next search, even on the same train line.
